IP 169.254.169.254 is not pingable , using route -n we could see an entry for 169.254.0.0. We tried to remove this entry using route del but again it reappear in next network restart. We are using ubuntu 12.04 LTS.

From horizon dashboard we can see a console asking for login in the following path instance - console. But we do not have the proper loginid and password for the created instance. We tried several combinations like (admin, blank) (root, blank) (ubuntu, blank) (demo, passoword) (admin, password) but none of them are working.

That would be Grizzly. In Grizzly there are two ways for the VM to reach the metadata server. One via a Quantum router and the other with DHCP. I haven't tried the DHCP way, but I believe it injects a route for 169.254 into the VM, but I don't know how it works after that - sorry.

I am also unable to ping instance "i-00000001" with ip 172.16.0.1 from client machine although I can ping from client(172.16.0.22)to server(172.16.0.21).
All the services are running on server nova-compute, nova-network, nova-cert, nova-scheduler, sshd, ports enabled.
I am getting error message:
ssh: connect to host 172.16.0.1 port 22: No route to host

We were unable to connect the instance using ubuntu username as well, but currently we are able to login using cirros test image. The metadata server 169.254.169.254 is still not accessible, curl http://169.254.169.254 shows the output as "Curl: (7) couldn't connect to host"
